The vacuum preloading technology is used commonly in engineering cases to treat soft soil foundation. In addition to the regular vacuum preloading technology, many kinds of modified vacuum preloading technologies are developed in practice. This paper analyzed the regular vacuum preloading, direct vacuum preloading and pressurized vacuum preloading technology in foundation treating effect based on in-site experiments in different areas in Tianjin Port. The comparison will benefit for other engineering cases in choosing a soft soil foundation treating plan suitable for engineering.
